What is the ruling on accompanying someone who openly commits adultery, despite repeated advice and her refusal to stop, and how should one deal with her when she believes that love can exist in the forbidden?

Adultery is a grave indecency, and the punishment for a married woman is more severe than for a virgin. This woman, in addition to committing adultery, openly boasted about it and showed off, which makes backbiting about her permissible. Since advice did not help, sever your relationship with her, for sitting with someone who openly commits sins is harmful and can lead to evil. Do not be deceived by the worldly blessings she enjoys, for this is a gradual enticement from Allah for the disobedient.
